Google app engine 使用ndb端点\u原型\u数据存储进行全文搜索

我一直在使用endpoints_proto_数据存储库来构建我的endpoints API，我试图找出如何返回从搜索API检索到的记录结果列表

@query\u方法似乎需要返回一个查询类型，它将在内部执行fetch调用。我将如何实现处理全文搜索的端点方法？我是否只定义一个定制的protorpc请求消息和响应消息，并跳过端点proto_数据存储库

这是我尝试过的，但得到了一个错误，列表没有ToMessage属性

Encountered unexpected error from ProtoRPC method implementation: AttributeError ('list' object has no attribute 'ToMessage')
Traceback (most recent call last):
  File "google_appengine/lib/protorpc-1.0/protorpc/wsgi/service.py", line 181, in protorpc_service_app
    response = method(instance, request)
  File "google_appengine/lib/endpoints-1.0/endpoints/api_config.py", line 1329, in invoke_remote
    return remote_method(service_instance, request)

    response = response.ToMessage(fields=response_fields)
AttributeError: 'list' object has no attribute 'ToMessage'

以下是代码的总体视图：

class MyModel(EndpointsModel):
  SearchSchema = MessageFieldsSchema(('q',))

  _query_string = None

  def QueryStringSet_(self, value):
    self._query_string = value

  @EndpointsAliasProperty(name='q', setter=QueryStringSet_)
  def query_string(self):
    return self._query_string


class MyServices(...):
  @MyModel.method(
      request_fields=MyModel.SearchSchema,
      name='search', path='mymodel/search')
  def SearchMyModel(self, request):
    return MyModel.Search(request.q)

如果您使用的是Java，那么答案就是使用

 import com.google.api.server.spi.response.CollectionResponse;

在python中，您需要创建
